Forecast: Thunderstorms likely Wednesday and Thursday; all eyes on Tropical Storm Arthur as it heads north

Hazy, hot and humid conditions are staying with us for two more days.The most likely days for thunderstorms are today and Thursday due to a cold front approaching from the west.

Behind this front, pleasant air is ready to move in once again. What will delay its arrival by a day is some tropical moisture flowing north along and ahead of the cold front that will try and push through on Friday. This will put the breaks on that front and slow it to a stop on Friday. This moisture is ahead of Tropical Storm Arthur. That storm will likely be located on the outer banks of NC Friday and heading southeast of Nantucket. It will impact our shoreline with swell, surf, and dangerous rip tides as well as heavy rain for Cape Cod, Boston, RI beaches and eastern CT.

A strong Canadian high pressure system to the west should have enough push to nudge all the showers east Friday afternoon with partial clearing locally on Friday evening. Good news for local fireworks displays Friday night. It may cause problems for displays from eastern CT to RI, Cape Cod, and Boston to Portland.

Today: Hazy and tropical again, afternoon and evening thunderstorms, High near 90.
Tonight: Early thunderstorms with some overnight tropical downpours. Oppressive humidity. Low near 72.

Thursday: Hazy and Tropical, numerous afternoon and evening thunderstorms. Some street flooding possible. High near 84.
